9 more than twice a number is 879

The number (x) in: "9 more than twice a number is 879" is what we are solving here.

In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 9, you get 879.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 879

Then you solve the equation by subtracting 9 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 9 = 879

2x + 9 - 9 = 879 - 9
2x = 870

2x/2 = 870/2
x = 435

Answer = 435

The answer above is correct, because twice 435 is 870, and 9 more than 870 is in fact 879.
